WATER-GAGE SHIELD.

Specification of Letters Patent.

To all whom it may concern:

Be it known that we, JAMES WV. LONEY and THEODORE C. STEGER, citizens of the United States, residing at FortWayne, 1n the county of Allen and State of Indiana, have jointly invented a new and useful ater-Gage Shield, of whichthe following is a specification.

Our invention relates to water gage.

shields intended to protect persons working in close proximity to such gages in locomotives on stationary boilers from in ury which might be caused by flying glass, steam and water, in the event'of the bursting of the gage glass tube.

I It is an object of our invention to over-. come this danger by providing a pipe for taking the steam and water out of rangeand further by providing a pressure tight shield.

It is also our object to provide a device that may be readily disassembled in the-event of the water tube breaking or for other reasons when desired.

It is an object of our invention to combine with such a shield improved means for holding a lamp in a suitable position to reflect light on the gage and to provide a form of lamp bracket to which adjusted and secured. j

It is also our object to provide a new combinat-ion and arrangement of parts, to .provide a safer and more efiective shield, and to. improve various parts of the device as described and illustrated.

Referring to the drawings, Figure 1 is a front view of our invention in use; Fig. 2 is a side view of same; Fig. 3 is a horizontal section on line 33 of Fig. 2; Fig. 41 is a perspective view of the band and lamp bracket; Fig. 5 is a vertical section on line '5-5 of Fig. 2; Fig. 6 is a horizontal section; Fig. 7 is a view partly in section, of a modified form of our invention; Fig. 8 is a plan view of member 3.

In the accompanying drawings, 1 1nd1- cates our semicylindrical metal shleld member, which may be made of aluminum, brass,

or other suitable metal; and 2 indicates a corresponding semicylindrical glass shield member, which may be of very heavy wire glass or plate glass, to 9; in thickness. The longitudinal edges of metal shield member l are provided with grooves holding rubber gaskets, indicated by 7,. 7, against which the longitudinal edges of glass shield corresponding brackets on the lamp member may be readily member 2 are The ends of shield members 1 and are pressed against rubber end gaskets 8, 8, which in turn are supported bymetal disks Patented a. 27, 1914,.

pressed. Adjustable shield bands 4, 4: having offset hinged portions, are

18, 18, and outer adjustable flanged" disks 3, I I

3, which screw up and down on threads on the gagecocks. The metal disks 18, 18, serve to prevent tearing of gaskets 8, 8 so that when adjustable flange disks 3, 3 are adjusted' a steam and water tight joint is effected at the ends of the shield members and the protection afforded. by the shield is increased. I

In meta-l shield member 1 we provide a discharge pipe 6 for conveying steam and water to ashpanyor pit of boiler and to in stantly release pressure in the shield in case of breakage of the gage.

In the draw1ngs,:1t willbe observed gaskets 10, l0'are' provided, disposed in interior grooves provided in'bands- 4, 4, as? illustrated, and which prevents the metal bands from contacting with the glass shield member and, rendering ,it liable to breakage in consequence. a

Ad'ustable flange disks 3, 3 are provided with extension bands 14, 1 1 that extend into the ends of the shield as to allow free adjustment of the packing nuts 15 to gage glass 16.

It is necessary that artificial means of lighting the gageglass be provided for use I at night, and that the light be so positioned as not to interfere wlth a View of the water tube. To accomplish this we provide lamp brackets 9, 9. Each has a vertical stem por tion attached to its band 4, and each terminates in a horizontally disposed flaring flange portion, as illustrated. The lastnamed portions of brackets 9, 9, are each provided with spaced orifices in which lamp bracket wires 17,17, are mounted. Their function is to secure a suitable lamp in place to illuminate the gage.

The operation of the device is indicated by the foregoing description in connection with the drawings.

It is essential that no water, steam or and are of such size" broken glass discharge in the locomotive cab or boiler room because of the fact that most gage glasses are stationed above the fire door, so that breakage of the gage glass would be liable to injure the man doing the firing. By providing discharge pipe 6, a means is afforded for taking steam and water out of range where it will do no clamage in case of accident. The arrangement of the gaskets between the shield members and at their ends permit the shields to be adjusted by means of bands 4:, 4:, and flanged disks 3, 3. In case of breaking of the water tube or for other reasons when it is desired to disassemble the device this may be done by revolving; flanged disks 3, 3 and loosening thumb screws 5, 5, which fasten bands a, t. The only tool required for the purpose is a small spanner wrench to hook in suitable notches in flanged disks 3, 3 to revolve same.

The foregoing description relates to my shield as applied to a boiler having two gage cocks, as shown in Fig. 1. Where there is only one gage cock in the boiler head and the top connection is made by a tube, a slight difi erence in flanged disks 3, 3, is necessary, as illustrated in Figs. 7 and 8. A bottom flanged disk 3 is provided with two ears 19, 19, having perforations 11, 11 for bolts. A similar top flanged disk 3 has similar cars 19, 19, but dilfers from disks 3 and from disk 8"* in that it is not provided with screw threads as are the other similar members. Bolts 12, 12 and wing nuts 13, 13 adapted to coact with bolts 12, 12 in operatively con necting disks 3 and 3" are provided. Ends of the shield members are made pressure tight by means of bolts 12, 12, which extend through the opposite eared portions of disks Copies of this patent may be 3 and 3 and are tightened up by wing nuts 13, 13 as illustrated in the figure showing this modified form of our invention.

What we claim is:

1. In a device of the class described, the combination of a semicylindrical metal shield member having a discharge pipe open ingout of its lower portion and having rubber gaskets disposed in grooved longitudinal edges of the said shield member, a cone:

sponding glass shield member, gasket lined adjustable bands fastening the shield members together, opposite lamp bracket members attached to the aforesaid adjustable bands and having horizontally-disposed perforated flange portions, and means connecting the aforesaid flange portions for holding a lamp.

2. In a water gageshield, the combination of a semicylindrical metal shield. member having a discharge pipe opening out of it,

and provided with gaskets on its longitudinal edges, a corresponding semicylindrical glass shield member, adjustable bands securing the shield members together, lampsupporting brackets mounted in the aforesaid band members, and means, including gaskets and adjustable disks, for closing the ends of the shield members and effecting gasketed water tight joints at the ends of the shield members, substantially as described.

In testimony whereof we hereunto set our hands 1n the presence of two witnesses. J AMES W. LONEY. THEODORE G. STEGER. Witnesses:
